"That's simple," observed London Bill. "I shall dig so as to undermine an end of one of those steel slabs that make the vault's floor, running my tunnel for the rear end of the vault. The weight of the gold will force down the slab when undermined. I'll open that vault like lifting the cover of a chest, only the cover will drop from the bottom instead of lifting from the top. The minute that slab of steel drops six inches, the sacks of gold will begin sliding into our tunnel of their own accord. You needn't worry about my part of the job; I can take thirty millions out of the vault if you can get them to the mouth of the drain."
"I can get them to the mouth of the drain," responded Storri confidently, "and another thirty with them. The real limit to our operations is the yacht itself. The one I have in mind will only carry one hundred tons, and thirty millions in gold makes sixty tons, to say nothing of ship's stores and coal."
"What place will you head the boat for when the job's done?"
"That," said Storri, "I shall leave to be settled in the open Atlantic. The question now is: Are you going with me? I've told you that your share is to be a million."
"One thirtieth?" said London Bill, with the ring of complaint in his voice.
"One thirtieth," returned Storri with emphasis. "Where else can you get one million for ten weeks' digging and a six-months' cruise in a yacht? Besides, there will be a dozen others to share; to say nothing of the yacht, and what it costs to coal her and buy her stores. Come now; do you go with me?"
London Bill put out a small, hairy hand, and gave Storri a squeeze of acquiescence that was almost a mate for the grip bestowed upon our nobleman by Richard that snow-freighted day in November.
"I'm with you, live or die," said London Bill; "an' I never weaken, an' never split on a pal."
Storri and London Bill put in an hour discussing plans. There were to be no more men brought into the affair until late in May. London Bill would come to Washington and commence his tunnel work at once. It would be a slow employment and require care; it was best to have plenty of time.
"Because," explained London Bill, "if these maps an' drawings ain't accurate to the splinter of an inch, it may throw me abroad in my digging. In that case I'd need an extra week or so to find myself."
